EVALUATION
It is not a regression. The test case is only affected. A fix will not change product binaries.
The problem is in the test itself. The test shows and closes several popup menus in a row. The "close" operation is performed with a pressing of the ENTER key. However, after the fix for 6217905, there is not any selected menu item in the menu and the ENTER key pressing cannot close the menu. This fact breaks the normal test flow.
A fix idea is simple. We should close the menus in a valid way. For example, the ESC key can be used instead of the ENTER key.
It is interesting that on Windows platforms the test doesn't fail.

EVALUATION
I cannot reproduce the problem on Windows XP with any JDK version. However, when I tried the test on Linux, it failed right away.
